TECHNICAL FIELD

In general, the present invention pertains to the art of transportation. In particular, the invention relates to disposable monolithic stackable containers with manually openable hatch for sample removal whilst in stacked conformation.

BACKGROUND ART

It is believed that the current state of the art is represented by the following patent literature: U.S. Pat. Nos. 2,054,785, 537,026, 4,056,210, 5,542,598, 7,340,995, US20110240657, US2013146602, US2015197374, US2016039598, US2016096667, EP2698322, GB2489326, GB1324670 and WO2014176292.

It is often desirable to randomly sample a fruit while it is in boxes or crates that are frequently stacked several layers high in ripening rooms or cargo shipment containers. Corrugated boxes and disposable plastic containers are typically cut open for sampling, using a knife. Such a procedure commonly used in the art is potentially damaging for the fruit and may lead to unnecessary contributing to further box failure and fruit damage. Conventional plastic containers, known in the art, however, do not have an optimal completely non-destructive means for fruit sampling when crates are stacked. Moreover, disposable plastic containers in the art are not known to contain a means for fruit sampling when crates are stacked. Furthermore, prior art teaches nether an effective means of forming a rotation hinge for the door of the hatch for sample removal nor a means of securing the door of the sample removal hatch in an open conformation.

US2016039598 and WO2014176292 teach a collapsible, reusable plastic container that can be used for the storage and transportation of produce. The container according to US2016039598 may also have a sample door with a clip for easy access to the produce contained in the container when it is stacked among other containers. The sample door of US2016039598 provides fruit graders with access to fruit in every crate on a pallet without de-stacking. The access door in US2016039598 can be opened and closed repeatedly throughout the life of the crate without affecting the structural integrity of the crate, the protection of the fruit (e.g., bananas) or produce in the crate, or the life of the crate.

US20110240657 teaches a reusable crate having a bottom and two respective pairwise opposing side walls and end walls, where the end wall has a thinned portion, so that the thinned portion is adapted to allow the user to cut the end wall for providing an inspection opening.

DETAILED DISCLOSURE OF EMBODIMENTS

Prior to elaborating any embodiment of the present invention, in order to present the background of the inventive concept more clearly, reference is firstly made to FIG. 1A, showing a hatch for sample removal known in the art, in wall 10 of the container disclosed in a more detail in US2016039598 and WO2014176292. Wall 10 with hinge 16 has an opening in which a door 12 is mounted in such a way that does not cut through the perimeter of wall 10. Such door 12 constructed from the same material as wall 10 is hingeably mounted or attached to the opening to allow the door 12 to pivot and be opened and closed. Opening the door 12 permits visual inspection and/or sampling of the product in the container, even when the container is within a stack of other containers on a pallet. The door 12 can be closed again, renewing the protective barrier that wall 10 to the contents of the container in storage or transport. Optionally, when door 12 is in the closed position, door 12 is coupled or attached to wall 10 by a clip 14 that prevents the door 12 from opening without user action.

The opening and door 12 in wall 10 and clip 14 having the form of a spring tang. The curved fruit sampling door 12 incorporates clip 14 that, when engaged, holds the door 12 closed and when disengaged allows door 12 to open to provide access to the contents of the container. Optionally, the clip 14 is a “low profile spring tang” mechanism which fits within the thickness of wall 10, not extending inside the curved surface of wall 10 or outside the plane as defined by the outside surface of wall 10. The mechanism of the clip 14 is reusable, allowing for repeated opening and closing of the sample door 12. The clip 14 is rotated outward to disengage clip 14 and allow door 12 to open. Door 12 and clip 14 are rotated inward with slight pressure to engage clip 14 and the latch bracket (not shown). Because of the door's 12 material, its hinged connection 18 and the use of clip 14 to secure it, the door 12 can be opened and closed repeatedly throughout the life of the container without affecting the structural integrity of the container, the protection of the product in the container or the life of the container.

To elaborate the background of the inventive concept of the present invention further, by depicting another hatch for sample removal known in the art, reference is now made to FIG. 1B, showing crate 100 disclosed in a more detail in US20110240657, notably requiring auxiliary opening or cutting tools to render the sample removal door open. As shown in FIG. 1B, each side wall 120 comprises a plurality 125 of vent holes, while each end wall 130 comprises a grip hole 135. Referring now to FIG. 1C, showing crate 100 with an openable portion. The end wall 130 comprises a thinned portion 910, where the thinned portion 910 may be configured as a groove. This groove 910 is made in the end wall 130 and surrounds at least three sides of a predefined area 905. As can be seen in FIG. 1C embodiment, the predefined area 905 is substantially rectangular. The zoom view shows that the groove 910 comprises a thickness I-(GR) in a direction perpendicular to the end wall 130, which is more than half of the thickness I(EW) of the end wall 130. This characteristic of the groove 910 allows for an easy cutting thereof. Furthermore, along the groove 910, a plurality 915 of holes may be arranged, wherein each hole may have a diameter 917 larger than a width 912 of the groove 910. The width 912 may typically be equal or larger than 6 mm. The dimensioning of the holes 915 is therefore such that a knife, which is commonly used by a controller, can be easily introduced into them and then cut along the groove 910. By cutting the groove 910, an openable portion 920 may be provided, which is essentially attached to the end wall 130. The openable portion 920 can be unfolded as indicated by the arrow. The purpose of providing such an openable portion is that the user can take a look inside the interior of the crate 100 for inspecting the accommodated products. For example, it can be checked whether carried fruits such as bananas have already reached a certain degree of ripeness. The end wall 130 may be made of plastic, such that a normal knife can be used by the controller. FIG. 1C shows also that the predefined area 905 may be more than one third of an area of the end wall 130 so as to provide a large enough inspection opening.

Illustrative embodiments of the invention are described below. In the interest of clarity, not all features of actual implementation are described in this specification. It will of course be appreciated that in the development of any such actual embodiment, numerous implementation-specific decisions must be made to achieve the developers' specific goals, such as compliance with technology- or business-related constraints, which may vary from one implementation to another. Moreover, it will be appreciated that the effort of such a development might be complex and time-consuming, but would nevertheless be a routine undertaking for those of ordinary skill in the art having the benefit of this disclosure.

In accordance with some preferred embodiments of the present invention, reference is now made to FIG. 2A to 2C, showing disposable monolithic container 20. Disposable monolithic container 20 is preferably stackable and comprises a bottom plate and two pairs of sidewalls. Disposable monolithic container 20 of the embodiment of FIG. 2A to 2C illustrates various features that may be interchangeable with elements of any other embodiment described in the specification.

Disposable monolithic container 20 is preferably monolithic. The term monolithic as referred to herein is intended to encompass any structure that is formed as a single piece. The term monolithic specifically excludes any multi-part assemblies, comprising a plurality of components that are manufactured separately. It is clarified that non-monolithic containers are not configured to be disposable monolithic, because the recourses required for manufacturing the different parts separately and assembling these parts together thereafter, into the entire assembly of the non-monolithic container ,renders such non-monolithic containers impracticable for being disposable monolithic and/or unsuitable for a single use.

Disposable monolithic container 20 comprises hatch 22, facilitating removal of a sample from disposable monolithic container 20. Sample removal hatch 22 is obstructed by hatch closures 24A and 24B. Hatch closures 24A and 24B comprise a mechanism providing for manually opening closures 24A and 24B. Exemplary mechanism providing for manually opening closures 24A and 24B embodies perforation pattern 26A disposed in-between the top edges of closures 24A and 24B and the top edge of hatch 22, perforation pattern 26B disposed in-between the bottom edges of closures 24A and 24B and the bottom edge of hatch 22 as well as perforation pattern 26C disposed in-between the diagonal edge of closure 24A and the diagonal edge of closure 24B.

It is noted that disposable monolithic container 20 is configured for sample removal via the hatch formed in the sidewall thereof. Therefore disposable monolithic container 20 is configured for sample removal via the hatch, whilst a plurality of disposable monolithic containers 20 are stacked-up and/or piled-up, one on top of another. This is contradistinctively to prior art, such as U.S. Pat. No. 4,056,210, where the opening is formed in the lid, covering the main top opening of the cup, thereby rendering the opening in the lid of the cup according to U.S. Pat. No. 4,056,210 inaccessible, when a plurality of cups with lids of U.S. Pat. No. 4,056,210 stacked-up and/or piled-up, one on top of another.

Perforation patterns 26A, 26B and 26C comprise essentially elongated gaps 28A, 28B and 28C interposed by detachable connectors 30A, 30B and 30C. Elongated gaps 28A, 28B and 28C as well detachable connectors 30A, 30B and 30C are preferably not equidistant. Detachable connectors 30A interconnect the top edges of closures 24A and 24B with the top edge of hatch 22, while detachable connectors 30B interconnect the bottom edges of closures 24A and 24B with the bottom edge of hatch 22, whereas detachable connectors 30C interconnect the distal diagonal edge of closure 24A with the distal diagonal edge of closure 24B.

Disposable monolithic container 20 further comprises hinge perforation patterns 32A and 32B, disposed in-between lateral proximal edges of hatch 22 and proximal edges of hatch closures 24A and 24B. Hinge perforation patterns 32A and 32B are configured to sustain partial rotation of hatch closures 24A and 24B, typically outwards disposable monolithic container 20, by being slightly bent or deformed, without disconnecting hatch closures 24A and 24B lateral edges of hatch 22 and while substantially maintaining structural integrity of hinge perforation patterns 32A and 32B.

Hatch closures 24A and 24B further comprise annular finger tabs 34A and 34B, facilitating initially disconnecting detachable connectors 30A, 30B and 30C of perforation patterns 26A, 26B and 26C, by pulling onto finger tabs 34A and 34B, as well as then driving hatch closures 24A and 24B into an open conformation (not shown), by slightly bending or deforming hinge perforation patterns 32A and 32B.

At least one of hatch closures 24A or 24B preferably further comprises a planar surface, such as planar surface 36 on hatch closures 24A, configured for inscribing miscellaneous information thereon, such as lot number, shipment date, etc.

Disposable monolithic container 20 preferably further comprises lateral grooves 38A and 38B. Lateral grooves 38A and 38B are configured to receive finger tabs 34A and 34B, in an open conformation, and lock the former within the former. Upon opening hatch closures 24A and 24B, by pulling onto finger tabs 34A and 34B and bending or deforming hinge perforation patterns 32A and 32B as well as by bending or deforming hatch closures 24A and 24B, finger tabs 34A and 34B are cable of being drawn towards lateral grooves 38A and 38B, respectively.

Upon introducing finger tabs 34A and 34B into lateral grooves 38A and 38B and releasing hatch closures 24A and 24B, hatch closures 24A and 24B are spontaneously locked within lateral grooves 38A and 38B, due to the elastic bias of perforation patterns 32A and 32B as well as the elastic bias of hatch closures 24A and 24B, thereby rendering hatch 22 in an open conformation (not shown) and facilitating sample removal from disposable monolithic container 20. Upon completion of sample removal from disposable monolithic container 20, finger tabs 34A and 34B are typically released from lateral grooves 38A and 38B by forcefully pulling finger tabs 34A and 34B away from disposable monolithic container 20 and hatch closures 24A and 24B are spontaneously driven by the elastic bias of perforation patterns 32A and 32B as well as the elastic bias of hatch closures 24A and 24B, into a re-closed conformation (not shown), essentially resembling to the closed conformation shown in FIG. 2A to 2C.

It is emphasized, however, that contradistinctively to the container disclosed in US2016039598 shown in FIG. 1, upon completion of sample removal from disposable monolithic container 20 and return of hatch closures 24A and 24B into a re-closed conformation (not shown), essentially resembling to the closed conformation shown in FIG. 2A to 2C, the mechanism of perforation patterns 26A, 26B and 26C still bears a clear indication vividly apparent upon visual inspection that hatch closures 24A and 24B have been tampered and/or opened since detachable connectors 30A, 30B and 30C remain disconnected and closures 24A and 24B typically remain slightly bent or disposed somewhat outwards hatch 22.

In accordance with some other preferred embodiments of the present invention, reference is now made to FIG. 3A to 3C, showing disposable monolithic container 40. Disposable monolithic container 40 of the embodiment of FIG. 3A to 3C illustrates various features that may be interchangeable with elements of any other embodiment described in the specification.

Disposable monolithic container 40 comprises hatch 42, facilitating removal of a sample from disposable monolithic container 40. Sample removal hatch 42 is obstructed by hatch closure 44. Hatch closure 44 comprises a mechanism providing for manually opening hatch closure 44. Exemplary mechanism providing for manually opening hatch closure 44 embodies peripheral groove 46A disposed in-between the top edge of closure 44 and the top edge of hatch 42, peripheral groove 46B disposed in-between the bottom edge of closure 44 and the bottom edge of hatch 42 as well as peripheral groove 46C disposed in-between the distal diagonal edges of closure 44 and the diagonal edges of hatch 42.

Peripheral grooves 46A, 46B and 46C comprise a portion of removed or lesser material, forming purposefully weakened connection between the top edge of closure 44 and the top edge of hatch 42, the bottom edge of closure 44 and the bottom edge of hatch 42 as well as between the distal diagonal edges of closure 44 and the diagonal edges of hatch 42. The purposefully weakened connection formed by peripheral grooves 46A, 46B and 46C rendering the top edge of closure 44, the bottom edge of closure 44 and the distal diagonal edges of closure 44 tearable or cleavable or otherwise disconnectable from the top, bottom and distal diagonal edges of hatch 42, respectively.

Disposable monolithic container 40 further comprises hinge perforation pattern 52, disposed in-between proximal edge of hatch closure 44 and respective edge of hatch 42. Hinge perforation pattern 52 is configured to sustain partial rotation of hatch closure 44, typically outwards disposable monolithic container 40, by being slightly bent or deformed, without disconnecting hatch closure 44 from the respective edge of hatch 42 and while substantially maintaining structural integrity of hinge perforation pattern 52.

Hatch closure 44 further comprises annular finger tab 54, facilitating initially disconnecting or cleaving the purposefully weakened connection formed by peripheral grooves 46A, 46B and 46C, by pulling onto finger tab 54, as well as then driving hatch closure 44 into an open conformation (not shown), by slightly bending or deforming hinge perforation pattern 54. Hatch closure 44 preferably further comprises a planar surface 56, configured for inscribing miscellaneous information thereon.

Disposable monolithic container 40 preferably further comprises lateral groove 58. Lateral groove 58 is configured to receive finger tab 54, in an open conformation (not shown), and lock the former within the latter. Upon opening hatch closure 44, by pulling onto finger tab 54 and slightly bending or deforming hinge perforation pattern 52 as well as by slightly bending or deforming hatch closure 44, finger tabs 54 is cable of being drawn towards lateral groove 58.
